Has anyone had problems with the MCI8 trailing tires wearing out the tire on the inside edge from half the tire to the sidewall? When I bought the coach the left trailing axle bushings were bad and the tire leaned in at the top but did not wear the tire very fast. I changed the cross over tube with a new one. Now the tire is staight. I put on about 6000 miles and noticed it wearing again. Went another 6000 miles and tire completly wore out. I installed a used regroovable tire and it wore the tire out in 3500 miles completely. Thanks in advance on any clues on what is happining. I did increase my down pressure on the loading of the tire long time before this to 42 psi to keep the brakes from locking up when the signal lights changed when You are 150 feet away

You still have a major alignment problem. As quick as your tire is wearing, you may have either loose, worn, or bent components.

You can check for the worn components by jacking the bus and wheel and looking for relative movements. You can also do a rough alignment check, but I would expect wear in the brass bushing or tube.
